Oh, how I would have loved to be part of something like this, but sadly, I don't have the time to post as often as a Casual roleplay tends to  demand.

I'm a huge fan of mythology, though. Especially the Norse, being a Dane myself ;) My daughter is actually called Freja after the Norse Goddess of Love/Fertility/Beauty/and-so-on and plan on naming my future children after Norse Gods/Goddesses, also. I'm thinking Thor and/or Balder for a boy and Idun and/or Sif for a girl (though I wouldn't have a Thor and a Sif both, since they'd get teased 'bout being a couple). I plan on having four kids and if I have it my way (which I probably won't) it'll be two girls and two boys and in that case they will be called Freja, Thor, Idun and Balder :D But that's just me rambling.

If you can live with a post a week (two, if I'm "lucky"), I will try my best to be a part of this, though.
In that case, I'd probably play a lesser God/Goddess, like Nyx of the Greek Mythology, or some actually quite famous deity that just has a bit of a messy history like... Tyr of the Norse Mythology, perhaps.
